Purpose

Substantiation of parameters of the conveyor transport system of the main cargo flow of the mine in the conditions of intensification of mining works, which are determined by the actual cargo flow in the coalfaces and on the basis of objective calculation.

Methodology

Achieving this purpose involves:
• conducting an analytical review in the field of conveyor transport systems of mining enterprises;
• conducting statistical research to establish the distribution of random cargo flow in high-performance coalfaces;
• conducting research to provide the specified productivity for the conveyor transport line.

Findings

Improving the efficiency of mines is one of the main tasks of the coal industry.

The decision of this question is connected with concentration of mining works at mine, development and improvement of underground transport.

Due to the intensification of mining works and the increase in the load on one coalfaces, coal mines with high-performance coalfaces have now been developed, in which conveyor transport systems of the main cargo flow are used.

The analysis of the work of these mines shows their insufficient efficiency, which is associated with the uneven cargo flow and the use of irrational parameters of the conveyor transport line.

Research has shown that to increase the efficiency and reliability of mining enterprises it is necessary to use the optimal parameters of conveyor transport lines. They must be determined by the actual cargo flow in the coalfaces, taking into account the influence of the speed of transportation of cargo.

• on the basis of statistical researches the theoretical model of distribution of a cargo flow in high-performance coalfaces in the form of asymmetric exponential function and possibility of definition of coefficient of non-uniformity is established;
• on the basis of theoretical and experimental researches the specified condition of realization by the conveyor transport line of the set traction effort and productivity taking into account influence of speed of transportation of cargo is established.

Keywords: concentration of mining works, cargo flow, unevenness, conveyor transport line, speed of transportation
